Abstract
A method of improving the quality of froth removed from a minerals separation flotation cell by providing converging side walls to crowd the froth into a narrower chimney and thereby increase the froth height. The riser is constructed so that the height of the froth from the pulp/froth interface to the froth overflow weir is greater than the natural froth height in a similar parallel-sided flotation cell.
